What is GOST 1050 Grade 20 Carbon Steel Seamless Tubes
GOST 1050 Grade 20 Carbon Steel Seamless Tubes are also known as mild steel pipes and tubes. GOST 1050 Grade 20 Tubes are low-cost Low Carbon Steel Tubes with 017-024 % carbon content with combination of 035-065 % manganese easy to form and shape .These pipes are manufactured as per GOST Specification and commercially referred as cs pipes or ms pipes.Low Carbon Seamless Steel Pipes or pre-honed tubes are not as hard as hig carbon steel pipes,Though carburizing can increase its surface hardness.
